To all whom, it may concer-n: l

Be it known that l., WiLLiAM R. J ni/ivoNs, residing,` at Cleveland, in the county of Cuyahoga and State of' Ohio, have invented a certain new and useful improvement in Oil- Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

My invention relates to oil-burners, and more .especially to burners wherein a blue ilame is produced without the provision of theperforated commingling-tubes that are ordinarily employed for the purpose ot produoing such flame.

The object ot the invention is to improve he eiliciency ot such. burners.

' More specilically stated, the object of' the invention is to provide eii'ective means whereby condensation of vapors on the burner parts is prevented, whereby the combustion is improved, and whereby the-burner is con- .kteniently supported in operative relation to 'its supply-pipe.

`Generally speaking, the invention may be defined as consisting of the combinations of elements embodied in the claims hereto annexed. I

Referring to the drawings, Figure 1 represents a vertical section taken through a burnerin accordance with my invention, the supply-pipe, the tank, and burner-clamps being shown in elevation. Fig. 2 represents a sectional detail ol a burner-clamp. Fig. 3 shows a perspectivev detail of the chimneysupportingr ring. Fig. i is a bottom perspective view o'l a portion ot' the chimney; Fig. 5, a side elevation of the spreader and its associated parts; Fig. 6, a'sectional view on the line4 (S (i of Fig. 1, and Fig. 7 an enlarged de tail of the top oi' the burner.

.Describing the parts by reference characters, 1 and2 represent, respectively, the'inner and the outer wick-tube oi iny'hurner. The. outer wick-tube is provided with an in tegrral 'Harige 3, located at a suitable distance below the top thercoi to engage the inwardly-extendingsupports 1 of the ring 5,

-which supports thc chimney and between which and said wick-tube air is supplied. to the ilame. The burner will be provided with the usual wich-raiser. (Not shown.)

The inner wick-tube is slightly shorter than the outer wick-tube, leaving a slightly greater area' of the wick exposed on the inside of the burner than on the outside thereof. At a suitable distance below the top of the ini at their center a ring or socket 9.

:employ an air-detleeting device consisting ner tube a supporting'and centering device is located. This device consists of an outer ring 7, which is secured, as by soldering, to the inner wick-tube. Projecting inwardly from said ring are the arms 8, which support Projecting upwardly from the rinsQr 7 are several. lugs or knobs 10,- the purpose of which wiii be here inatter set forth.

The inner wick-tube is substantial-y open from top to bottoni thereof, wher yhy said tube constitutes a draft-tube for th interior supply of air. To distribute the ai, properly to the tlame, on the inner side of tne wick I generally of a spreader 11, a vertically-extending ring 12, and a perforated irusto-conical ring 13, united to said spreader and the lower portion of the ring 12. f

The' spreader is preferably oit sheetsteel,.. and its central portion 121 united to the top of the perforated ring` 13 by bolts and nuts 15 in this ease, though rivets or other suitable means oi fasteningr maybe used. Airb passages 17 17 are provided in the central portion oiv the spreader ier the passage of a limited volume of air to the gases which rise above the spreader to complete the combustion thereof. From the central ortion the spreader is preferably slightly inc ined down-- wardly to a point above the wick, the outer` edge of the spreai'ler being substantially in a vertical plane with the outer edge of the outer wick-tube and only a short distance thereabove. i

The ring` 12, as previously stated, is secured at the lower end to the supportingring 13. 'The diameter of said ring 12 is slightly less than the inner diameter of' the tube 1whereby the annular air-space 18 is provided between saidwr'ing and tube. The upper portion of the ring 12 is deiiected inwardly at 19 and extends slightly above the top oi" the outer wieletube. 2. Between such inwardly-deileeted portion of the ring 12 and the inner wick-tube tl ere is provided an enlaneed space 20, wherein the air which supports the primary er wick iame is protected i'roni the rapidly moving; air-current passing iroin the center of the ring 12 outwardly under the spreader. The lower end ot the ring` re ts on the lugs 4or projections 10, whereby a restricted annular passage 21 is provided lietween the ring 7 and the base of the ring 12 for passing a very limited supply of air to the space 18. it will oe noted tiet' ICO v m tht"A Supiwrii L15-ii hum@ mm mit! at' thv man@ it: thv ring 72 thv tiistuu-O nii* but um :iti hay@ ci! tht` uppfl' muis of thvI 2L? fitli-titihva and muy; 1.2 :1mi thv :spv whim' muy ha Quin. tu wit mi hss than :1y

25, and reduced upper portion 26, extending about oneeeighth of an inch above the plane of the top ofthe wick-tubes and above the plane of the ring 12 and spaced about one-eighth of an inch from the outer wick-tube- `An annular seat 27 Ais'piovided at the base ofthe vertical portion 24'for the support of the chimney 6. The lower end of said chimney is curved inwardly, as shown at 28, and is provided at the bottoni with the substanitally horizontal flange 29, whereby j .said chimney is supported on the seat 27.

tends in a substantially horizontal direction and is there provided' with openings 30 fr the admission of air to the outside of the flame issuing through the narrow space between the outer edge of the spreader 11 and the top of the ring 5. It frequently happens, however, that adisagreeable humming noise is produced by the operation of the burner. This may be overcome by supplying an increased volume of aii to the outside of the ilaine'through .openings in the ring 5. When this air is supplied only through openings located in the lower portion of the outer chimney, it is necessary .to adniit it in lsuoli measure as wotv v" tend to dilute the heat and correspondingly reduce the etliciency of the burner. I am enabled to overcome this defeet, however, by providing the restricted openings 31 inithe portion 24 of the ring 5 immediately above lthe point of support of the chiiniiey-.. V 4A small quantity of air from between the wick-tube 2 and ring 5 The point of admission of this additional 'supply of air and the direction Agiven'to it enable me to avoid the disagreeable sound referred to itliout cutting down the heating eflicienoyof the burner.

I have also provided means whereby the burner may be firmly but detaehably secured` to the supply-pipe, whereby stoves having my burners applied thereto may be shipped without danger of breaking the connections between the fuel-supply and the burner. For this purpose I employ the following construction: 432 designates a short connection.

`or conduit projecting laterally from the thinible 34, the said parts forming an oilpassage from the main pipe to the wicktubes. To secure the burner to the pipe and to maintain the thimble and nipple in ener- Theil lower portion of the curved portion 28 en-` With the parts as above described it irequently happens that from the engagement of the pipe by the inner head of the rivet 42 or from other reasons the strap is not propverly positioned on the pipe-that is to say,

that part of the strap opposite the lower end o'f the bolt 43 does not engage the extreme lower portion of the pipe, whereby on setting upzthe bolt 43 the strap will be twisted from the position shown in Fig. 2, with one niember of the strap bearing closely against the pipe and the top of the nipple, whi le the other member is bowed outwardly, thereby making an insecure connection between the supplypipe and the burner. To obviatc this objection, I provide each of said members with an inwardly-extending lower portion 45. This portion is curved inwardly toward the pipe, whereby it may engage the saine, and is made of iieXible material, permitting it to bend outwardly when the bolt is tightened, Moreover, this shape of the lower end of the strap keeps the head of the rivet from primarily engaging the pipe, and thus prevents the strap trom improperly binding itsehc on the pipe relative to the nipple and the thimble.- The ordinary pipe of commerce varies considerably in outside size; but by reasoiiof the strap having llexible sides and made ol a size'to easily slip ovei the largest size pipe it is easily moved into position, andthe flexible sides of the strap draw in and closely hug the sides of the pipe when the bolt 43 is tightened into place. By reason also of the ilexibility. in the strap the bolt 43 does not beconie loose it unscrewod slightly from its position against the nipple, so that even it said bolt is screwed against thc nipple with but moderate torce for holding the burner iii place there is no probability ol the holt ho-V coming loose bv the jarring incident to shipping and handling, as would be the caso it there were no flexibility in the strap.

The portion of the burner opposite tl ie connections 32 is provided witha hook, the upper portion 4S ol! which is secured, as by soldering, to the inside of the wick-tube l. Sonie of' the solder may be applied to the bottoin of the wick-tubes, as shown at 49, thereby forming a seat which protects the same from wear against the pipe 35. The shank ol this hook is bent outwardly at 47, along side oi the pipe 35, to forni abearing against one side thereof, and is then bent downwardly IOO :intl inninrrhy to forni the hoo rho npvfn: ftljo?
